APPARATUS FOR BURNlNG PETROLEUMDOILS, 34C.

SPECIFICATION forming part of Letters Patent No. 476,560, dated June 7,1892.

Application tiled October 17. 1890. Serial No. 363,428. (No model.)

To all whom it may concern.-

Be it known that I, OswALD R. ROUTE, of Jersey City, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovements in Apparatus for Burning Petroleum-Oils, the.; and l dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to apparatuses designed to be used in place ofthe usual grates in the fire-pots of common stoves, heaters, furnaces,thc.; and its object is to provide asafe and economical means wherebykerosene and like petroleum-oils or liquid fuels may be used as fuel insuch stoves 0r other heaters, the latter affording the means of asuitable draft to the flame and also on occasion support in the usualway for cooking utensils or other articles to be heated.

This class of apparatus should have a high degree of utility inasmuch asa properly-constituted petroleum-oil flame is capable when placed in thefire-pot of an ordinary cookingstove or other suitable place or fire-potnot only of heating griddles or other articles or vessels placed aboveit, but also of heating the oven or ovens in much the same manner as theflames of wood, coal, or other solid fuel. To secure an ehicient flamefrom petroleum-oils, however, for such uses, it is desirable that thelatter be converted by heat into gas or vapor before ignition; but inapparatus of the class mentioned prior to my invention the gas or vaporleft in the vaporiZing-chamber after the extinguishment of the llame hasbeen a source of danger, frequently causing explosions when the flame isrelighted by reason of the gradual admixture of atmospheric air with thecontents of the gas or vapor chamber to form an explosivemixture whenthe apparatus is not in actual use.

My invention comprises certain novel combinations of parts, whereby thisliability to explosion is prevented, and an ecient and safely-operatedapparatus for burning petroleum-oils and like liquid fuels is provided.

Figure l is a longitudinal vertical sectional View, and Fig. 2 is atransverse vertical sectional view, of an apparatus embracing my saidinvention and showing the same duly located in the fire-pot of acooking-stove. Fig. 3 is a detail view of some ofthe parts of saidapparatus.

A is the fire-pot of the stove, in which the apparatus is to be placedfor use, as shown in the drawings.

B is a chamber into which, through a pipe C, the petroleum-oil orliquidfuel is supplied 6o from a tank D, which should be placed at such aheight that the oil may flow readily to said chamber B. From the lowerpart of said chamber extends a pipe or tube E, the main length of whichis brought to ahorizontal position, as shown more fully in Fig. 2, andwhich is perforated with numerous small holes. Placed below thisperforated horizontal tube, the outer end of which is closed, orSubstantially so, is a pan F, in which is placed 7c a mass G of asbestusor like material. This mass G constitutes what may be termed akindling-burner, inasmuch as it is so provided and arranged withreference to the perforated pipe as to receive therefrom a quantity ofoil sufficient byits combustion to bring the oil in the chamber to avaporized condition. Then the oil ceases to be supplied to saidkindling-burner, the vaporized fuel is causedto pass out from theperforations of 8o said pipe and is ignited at said perforations by theflame from the kindling-burner. It will be noticed that the supply ofvaporized fuel at said perforations necessarily precedes the exhaustionof the oil, which has been sup- 8 5 plied to said mass orkindling-burner G, as described. The liquid fuel being supplied to thechamber B passes down through the openings or perforations in the tube Eupon the mass G of asbestus. It is ignited upon the 9o latter and theflame heats the chamber B, so that the oil or liquid fuel in the latteris vaporized, and the thus-generated vapor escaping through theperforations in the pipe E is brought in contact with the llame,and isthus in its turn ignited and continues to burn above the asbestus untilthe supply of oil is turned off, the gaseous products of combustion fromthe flame passing off through the adjacent flues or smoke passages 0fthe stove. roo

From the pipe C extends a branch pipe H, which leads to any suitableexit-as, for example, the j ust-mentioned iiu'e or smoke-passages of thestove. At the junction of the pipe H with the pipe C is the seat of athreeway cock, and a three-way cock I is placed thereat and in suchrelation with the pipes II and C that when turned to one position itwill shut off communication between the pipe H and the pipe C, leavingopen communication between the tank D and the chamber B, and when turnedto another position will shut oif communication between said tank andchamber and open communication between the chamber and the pipe H, whichlatter, being open at its remote end, permits the escape of all vaporsfrom the chamber when the cock I is turned to the last-named position.

It will be observed that by the construction and operation above setforth communication between the tank and the chamber is closed when theflame is extinguished and this closing of said communication isaccomplished simultaneously with the opening of the pipe II, so that thelatter permits the escape from the chamber of whatever vapor may have remained in it at and after the extinguishment of the flame. The chamberbeing thus immediately emptied of vapor, the formation of explosivecompounds in said chamber is prevented and all danger in starting theapparatus into renewed operation and relighting the dame below thechamber is avoided.

To prevent any back-pressure ot' vapor in the chamber B when theapparatus is in use, the pipe C is provided with a check-valve K, whichopens toward said chamber and closes toward the tank. Any ordinary orsuitable construction of check-valve, provided it be arranged as j ustindicated, may be employed.

Over the mouth a of the pipe C, where the same connects with theinterior of the chamber B, is placed a cap, cone, or dome b of finewire-cloth, and the said chamber is internally divided by any desirednumber of partitions c, also of fine wire-cloth. rlhe cap or dome b andthe partitions c prevent the volume of vapor from its great mobilityfrom passing too rapidly through and from the chamber into theperforated tube or pipe E, thereby insuring a more equable andproperly-controlled supply of the vaporized fuel at the outlets orperforations of said tube or pipe. Said wire-clotl1 partition orpartitions also prevent the volume of vaporized fuel from pressing backtoo forcibly against the column of oil or liquid fuel in pipe C. By thussubstantially preventing back-pressure against the column of descendingoil the normal supply of oil from the tank to the chamber through thepipe C is assured. It is of course to be understood that the apparatusmay be used not only in connection with the tire-pot of a common stove,as described, but may be used, also, in any snitably-constructed casingwhich will provide the requisite draft of air to supply the flame andthe requisite outlet for the escape of the gaseous products ofcombustion-as, for example, the fire-bex of a boiler-furnace or othersuitably-arranged furnace, heater, or the like. In order to enable theoil in the tank D to be shut oif entirely, when desired, from the otherparts of the apparatus, the pipe C may be provided with a common valveor stop cock L for such purpose.

Vhat I claim as my invention is l. In an apparatus for burning liquidfuel in stoves or other heaters, the combination, with a supply-tank, ofa gas-forming chamber, a pipe connecting them, another pipe havingvalved connection therewith and having an open end adapted toenteraflne, and a burner located beneath the chamber and connectedtherewith.

2. In an apparatus for burning liquid fuel in stoves or other heaters,the combination, with a supply-tank, of a gas-forming chamber, a pipeconnecting them, an outlet-pipe connected thereto, a three-way cock atthe junction adapted to open communication only between the tank andchamber or between the chamber and outlet-pipe, and a burner lo` catedbeneath the chamber and connected thereto, so as to receive its supplytherefrom.

3. The combination, with thetank D,cham ber B, pipe C, perforated tubeor pipe E, and kindling-burner G, constructed and arranged as described,of the branch pipe H, extended from the pipe C, and the check-valve insaid pipe C, all substantially as and for the purpose herein set forth.
